We report the discovery of a new X-ray transient AGN, RX J1624.9+7554. This object appeared to be bright in the ROSAT All-Sky Survey, but had turned off in two pointed observations about one and a half years later. The optical identification spectrum shows a non-emission line spectrum of a spiral galaxy at z=0.064. We will discuss several hypotheses that can explain the peculiar behaviour of th...

Other recent stud...

On January 19, 1996 we published in the Internet a demo of how to use Self-Organizing Maps (SOMs) for the organization of large collections of full-text les. Later we added other newsgroups to the demo. It can be found at the address http://websom.hut../websom/. In the present paper we describe the main features of this system, called the WEBSOM, as well as some newer developments of it.
